On 3.8 the PVC valve is located to the right of the power steering pump, under a 2 inch black cap, left of the intake. It blends in quite well. The spark plug wires run between it and power steering pump.

My 97 chevy lumina recently started to idle high it will actually drive itself shifts hard and not into every year and only my right front brake works


The high idle problem could be a stuck idle air control valve or a major vac leak. Something like the vac hose going to the power brake booster for example.
The computer controls idle speed with the idle air control valve.
Extra air may be entering the intake beyond that control valve.

Idles too high at start, then too low after warmup.


Did you have it diagnosed by a scanner of some time? Sounds like you are pulling/replace instead of diagnosing the issue prior to fixing. You probably have a bad IAC sensor, but it could also be the throttle position sensor. Do have a check engine light when it does run? How many miles are on the vehicle. it could be a timing issue. I had a 95 Lumina and it turned out to be a sensor, but mileage does play a key in this issue.

Lumina z34 idles at high rate can not solve please any help


check and clean idle air control. clean where it mounts to engine and also the valve. do not put in any solvent, only clean tip of valve. an old tooth brush works fine for this. do not push on tip while cleaning, it will mess up the idle setting.
